  • Interfacing a 4x4 Matrix Keypad with an 8-Bit GPIO Expander
    AN1081 Interfacing a 4x4 Matrix Keypad with an 8-Bit GPIO Expander * I/O Direction Register (IODIR): The IODIR Author: Mike Curran register controls the direction of the port pins. A Microchip Technology Inc. high on the corresponding bit configures the pin as an input and a low configures
  • Low-Voltage 16-Bit I2C and SMBus I/O Expander with Interrupt Output, Reset, and Configuration Registers (.pdf)
    This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed to provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL) and serial data (SDA)]. The major benefit of this device is its wide VCC range. It can operate
  • The RS-232/DALI Bridge Interface
    at lower power levels than standard magnetic ballasts. With the rise of digitally controlled ballasts, the need for devices that ?talk? to them has increased as well. This application note describes a very simple interface between the RS-232 serial port (available on almost all computers) and DALI, where
  • Case Study: PSCUFS Implements Avocent Solutions for Data Center Overhaul
    . PSCUFS's access to serial devices also came under scrutiny. Access to equipment such as switches, firewalls and routers was only achieved through at-the-rack connections to the console port of each device.
  • USB Embedded Host Stack
    the bus expanded through the use of hubs. USB is a tiered star on which one or more devices communicate. The most network. Typically, a hub allows four or seven devices common USB host is a PC. With the introduction of to attach to a single port. A maximum of five hubs can Microchip's microcontrollers
  • An Innovative Cabling Concept Improves Reliability for Multi-Axis Stage Systems
    , and encoders are integrated. Alternatively to CAN open, the communication with a master computer may be executed via a serial port (RS232). By miniaturizing the electronic PCBs, the size and mass of the individual control boxes is smaller than a comparable cabling system. For the 3 axis XYZ system
